Properties

empty → T
Return the identity element for this monoid.

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

Methods

combine(T x, T y) → T
Associative operation which combines two values.
inherited
combineN(T a, int n) → T
Return a appended to itself n times. If n is negative, then this returns inverse(a) appended to itself n times.
inherited
intercalate(T middle) → Semigroup<T>
Return a Semigroup which inserts middle between each pair of elements.
inherited
inverse(T a) → T
Find the inverse of a.
inherited
isEmpty(T a, Eq<T> eq) → bool
Tests if a is the identity (empty).
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
remove(T a, T b) → T
Remove the element b from a.
inherited
reverse() → CommutativeMonoid<T>
Return a CommutativeMonoid that reverses the order.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

instance<A>(A emptyValue, A f(A a1, A a2), A inv(A a)) → CommutativeGroup<A>
